That will work in a 55g. Better to have more than few at the beginniing; as they settle and grow you can always remove some.
The pygmy chain sword will eventually require regular thinning; once settled (which can take a couple months sometimes) it will rapidly send out runners. I have this plant in all my tanks, and all from one plant I bought 3 years ago; it is superb as a small plant, grows rapidly, looks nice. I toss out clumps regularly.
The larger Vallisneria (last two) may do the same, and as they get very large, will need to be controlled. But I always think it is nicer to have to pull plants out rather than having them struggle and fail.
